In recent years, central banks and international organisations have been making ever greater use of factor models to forecast macroeconomic variables. We examine the performance of these models in forecasting French GDP growth over short horizons. The factors are extracted from a large data set...

[spa] Reseña acerca de los tests de rationalidad, . por Catherine Doz.. . En esta reseña se examina el principio de los tests de sesgo de las previsiones y las dificultades que se plantean a este respecte Ahora bien, los resultados de estos tests deben considerarse la mayoría de la veces con...

[ger] Die Verwendung der VAR-Modelle zu Prognosezwecken, . von Catherine Doz, Pierre Malgrange.. . In diesem Artikel soil die Eignung eines als einfacher "schwarzer Kasten" verwandten VAR-Modells zu Prognosezwecken bewertet werden. Die Schätzungsergebnisse führen zu einem VAR-Modell mit...

[spa] Veinte años de previsiones macroeconómicas : un anlisis a partir de datos Franceses, . por Didier Borowski, Carine Bouthevillain, Catherine Doz, Pierre Malgrange y Pierre Morin.. . En el presente artículo se examina el grado de precisión que han alcanzado las previsiones...

[fre] L'analyse des séries macro-économiques repose généralement sur une décomposition en tendance et cycle. Cet article est consacré à l'examen de méthodes purement statistiques d'extraction d'une tendance et d'un cycle à partir d'une série brute ; il se limite aux techniques...

Is maximum likelihood suitable for factor models in large cross-sections of time series? We answer this question from both an asymptotic and an empirical perspective. We show that estimates of the common factors based on maximum likelihood are consistent for the size of the cross-section (n) and...

We suggest a two step procedure to estimate a dynamic factor model. We show that, in a stationary dynamic framework, static factor analysis leads to consistent estimators and allows to build an asymptotic test of the relevant number of factors. Once this number is set, the model can be estimated...

This paper presents a study of the finite sample properties of the pseudo-maximum likelihood estimators in the case of a Poisson model. The simulations have been realized with control variates, a method which has considerably improved the accuracy of the results obtained. The negative binomial...

This paper shows consistency of a two step estimator of the parameters of a dynamic approximate factor model when the panel of time series is large (n large). In the first step, the parameters are first estimated from an OLS on principal components. In the second step, the factors are estimated...

This paper considers quasi-maximum likelihood estimations of a dynamic approximate factor model when the panel of time series is large. Maximum likelihood is analyzed under different sources of misspecification: omitted serial correlation of the observations and cross-sectional correlation of...
